My personal Recommendation.
It always depends what you use a laptop for, if your talking high end processor, your not talking battery life.
For the "portable" that is in the large laptop range, this would generally sit in one place but be easy to move or stow if you had to, look to HP.
AMD is nice, but you get tied to manufacturers, and if the HP model had an AMD in it I would be even more inclined to get it. But the size and quality of the monitor, the DVD burner included, the vidio excetera make this an awsome laptop for the price. If your looking for something that is not a micro machine you take anywhere, but rather a computer you can make dissapear from your desk top at any time, then this is a prime choice.
If you need power you can take a "HyperThreading" processor which probably gives you a 20 % boost over a similar processor.

Best of all is the price ($1400). My sister has one, and it's nice to work on.
Battery life is on the 1 - 3 hour range, so maybe it is not the best choice.
Opps it does not have a DVD burner, but for the price you can always by an external one, it does have a DVD player/CD-RW drive installed.
Personally for the customization options, I'd take the slowest processor, 1 gig memory, and XP professional. Higer res monitor is a nice plus for only $75.
